In this Way we are able to re-shape amount of predetermined design which has just been fabricated and obtainamount of different design Without the necessity for building a Wholenew mount machine. The apparatus ,of our invention is mounted on a tableM which is, in turn, mounted on the main frame of the mount machine.However, if desired, the table 14 may be eliminated: and the apparatusmounted directly on the mount machine frame. The zipparatus" ispositioned on the mount machine so that its mount re-shaping mechanismswill engage the mounts which are held in the heads of the mount machine.

In Figures 1, 2 and 3 a pair of standards I6 and I8 mounted in blocks Iand I1 respectively aid in supporting a first shaper assembly 38 and asecond shaper assembly 39 respectively through guide blocks 20 and 2|respectively.

The first shaper assembly 38 comprises a shaper cylinder 32 with ashaper cone 5 slidably mounted on one end thereof. The shaper cone 5 isfixedly mounted in a block 4 and its position therein may be adjusted bymeans of a screw 66. A pair of adjustable drive links 21 are connectedat one end thereof through universal joints 28 to the block 4. The otherend of each of the drive links 21 is connected through universal joints26 to a bearing shaft 25 which extends through one end of an actuatinglever 2.

The shaper cylinder 32, which is supported by the block 2:: through abushing 9, is provided with an elongated slot 33 therein and the shapercone 5 is provided with an aperture 40 in register with the slot 33. Apin 34 for driving cylinder 32 during a portion of its stroke, andkeeping the shaper cone 5 oriented thereon extends v through theaperture 49 and into the slot 33. The upper end of the shaper cylinder32 is hollow and the wall thereof is slotted to define tongues 4 I.

A lead wire separator 31, an inverted L-shaped member, is mounted on thetop of the shaper cylinder 32, the base portion thereof being connectedthereto by a screw 43 and the leg portion thereof extending downwardlyalong the outside wall of the cylinder 32. One end of a link In extendsinto an aperture 44 in the base of the cylinder 32 and the other endthereof is connected to one end of a spring-loaded lever I through auniversal joint The second shaper assembly 39 comprises a haper cylinder3| with a shaper cone I9 mounted on the upper end thereof, and a leadwire separator 45 disposed in th cone I9 and secured in position thereinby a screw 46 (Figures 5 and 6').

The shaper cylinder 3| is supported by the block 2| through a guidebushing 41. The shaper cylinder 3| is connected to one end of anactuating lever |3 through an adjustable drive link 36. The

ends of the drive link 36 are provided with universal joints 29 and 30,the joint 29,being conr nected to the actuating lever I3, and the joint30' being connected to the lower end of the shaper cylinder 3 I.

As was mentioned above, the front end of the actuating lever 2 supportsthe bearing shaft 25,

the front end of lever I is connected through universal joint II to linkI 0, and the front end of actuating lever I3 is connected through theuniversal joint 29 to the adjustable drive link 36. The rear end oflevers 2, I, and I3 are mounted on a shaft I2 which is supported byjournals 23. The journals 23 are mounted on a bracket 22 which extendsupwardly from the table l4 (Figchine frame, and the other end of thelever 48 is connected to a suitable actuating means 50, such as a cam,for example.

An adjustable stop I, which consists of a screw threaded through theactuating lever 2, defines the end of the return stroke of the lever 2.An adjustable stop 6, which consists of a screw mounted in a bracket 8,defines the end of the first phase of the upward stroke of the shapercylinder 32. The lever I is provided with an arm 61, the free end ofwhich is engaged by lever 2 to insure a positive return of the lever I.

Figure 10 shows a mount 5| of a type which can be re-shaped by theapparatus of our invention to provide a mount 52 like the one shown inFigure 11. Similar reference members have been used to identify theseveral elements of the mount 5| of Figure 10 and the mount 52 of Figure11, except that, in the latter case, an alphabetic character has beenadded. The mounts 5| and 52 comprise a tube 53, one end thereof having aflared portion 54, and the other end having a stem press 55 in which aportion of lead wires 58 and 51 are sealed. The tube 53 is provided withan aperture 58 therein to which an exhaust tube 59 is connected forevacuation purposes. One end of an arbor 60 is fused to the top of thestem press 55, the other end thereof being provided with a button 5| inwhich an end of filament support wires 62, 63, and 64 are fused. Theother ends of the filament support wires 62, 63 and 64, and the adjacentends of the lead wires 56 and 51 are deformed to define loops and hookrespectively through which a coiled filament 65 of tungsten wire issupported.

A was mentioned above, the apparatus of our invention may beincorporated in conventional lamp mount machinery of the type shown inOtaka 1,821,894 and Flaws 1,907,532, for example, at a point after thelast fabricating position thereon, and thereby effect a re-shaping ofmounts like the one shown in Figure 10 to give a mount like the oneshown in Figure 11. When a head of the mount machine, from which themount 5| is supported during the several mountforming operations,carries the mount to a position where it is disposed above and inregister with the first shaper assembly 38, said assembly moves upwardlyand engages the mount 5 I.

- fects the upward stroke of the first shaper cylinder 32 and the firstshaper cone 5 independently of each other. This movement is transmittedto the cone 5 through the bearing shaft 25 and the drive links 21 whichconnect the bearing shaft 25 to the block4 in which the cone 5 ismounted (Figure 1) The upward movement of the actuating lever 2 istransmitted into the upward stroke of the first shaper cylinder 32through the spring loaded lever I one end of which is rotatably mountedon the shaft I2, on which the actuating lever 2 is fixedly mounted. Theupward movement of the actuating lever 2 effects an upward movement ofthe lever I through the spring 35 (Figures 2 and 3). The first shapercylinder 32 is connected to the spring loaded lever I through theuniversal joint II and the link I0, one end of which slidably-fits enguethe base of the eyimuer 32 (Fillif' i thecylmder 32 .is-notfi'x'edi'y'i'i'iounten on the link It, we have provided means forpreventing rotation thereof to make sure that it will-always engag'e themount 51 in a predetermined manner, with the tongues M "engaging thefilament support wires 82 and 64 and-the elongated slot 68 therebetweenproviding a free path for the filamerit support wire 63. This means=tonsists of an elongated rod (not shown), one end of Whichis fixedlymounted in a collar 59 which is in turn fixedly mounted on cylinder 32;which extends through an aperture therefor in the Supporting block"(Figure 1).

The upward stroke of the first shaper assembly 38 is. divided into threedistinct phases. In the first phase, the first shaper assembly 38, i.e., the shaper cylinder 32 and the snaper con5, move up together andengage the mount 5!. The end of the first phase of the strokeis definedby the Stop 6. Thus when the sprihg' loaded lever 'l' has moved up to apoint where it engages the screw 6, the first phase of the stroke hasbeen com-- pleted The relative position of the eylinder- 32 and the cone5, and the disposition of the-mount 5| at the one of the first phase ofthe stroke is shown in Figure 7. The lead Wires 56 and 57 and thefilament support wires 52, 63 and 64 have been moved inwardlyby theirengagement with the inside wall of the shaper cone 5. Filament sup--port Wire 63 is in register with an elongated slot 68- thus preventingdeformation thereof by the tongues 4L The tongues 4| have movediIltOfiO- sition to engage and deform filament support wires 62 and 6which will serve asthe lower filament supports of the mount of Figure11.

The'secondphase of the upward stroke or the first shaper assembly 38consists ofa furtherrupward. movement of the shaper cone 5 while theshaper cylinder '32 remains stationary. The length or this phase or thestroke is equal to the distance between the pin 34 and the top of theelongatedslot 33 as these parts are shown in Figure 1. Thus the upwardmovement of the shapelcone 5, while the shaper cylinder 32 remainsstationary is made possible by the manner in which the cone 5 is mountedon the cylin= der 32-. The relative position of the cylinder 32 and thecone 5, and the disposition of-the mount 5! at the end of the secondphaseof the stroke is shown in Figure 8. The cone 5 has moved up tofurther encompass the mount, and efieet a further inward displacement oflead wires 56 and 57. and filament support Wires 62, i3- arid B4.

The third. phase of the upward stroke of the first shaper assembly 3%consists of anupwa'r'd movement of both the shaper cone 5 and theshe-per cylinder 32. The pin 34 (Figure 1), which moved up to the top ofthe elongated slot 33 in cylinder 32 during the second phase of thestroke, serves as the cylinder drive pin during the third phase of thestroke, urging the cyIinderC-"Z upwardly with the cone 5. The upwardmovement of the cylinder 32 during this phase of the stroke is madepossible by reason of the fact that the link iii siidably fits into thebase thereof. Figure 9' shows the relative position of the cylinder 32and the cone 5, and the disposition of the mount 5| attire end of thethird and final phase of the stroke of the first shape]? assembly. H

The third phase of the stroke effects a further gathering of'the mountand the shaping of fila menu supra-orbs t2 and st to form thelowerfilasupports. As the cone 5 andthe cylinder $2 move upwardly theends of the lead Wires-:56

and 5? cushion the filament 65 is mounted are engaesdey the lead wireseparator Hand are duided'therebyto ih'siir'e then-user alignment anddisposition thereof. Further gathering of the rhount is aoeeinpiished bythe upward move or the cone 5 thereby encompassing a greater portionthereof than was encompassed by the second phase of the Stroke. shaping"Of the filament supports G58 and E i is effected when th tongues i!move into engagement therewith and continue their upward movement.Engagementor the filament supports $2 and 64 by the tongues 41 causesthe supports to bend at the points of e'ng'agement. Further upward mete-Iheiit or the tongues 41 deforms the filament S1115 ports 32 "anl'iifigteasing thmto bend back on themselves, and form the lower filamentsupports "as sh'ovvid iii Figure 11.

After the third and final phase of the stroke (if the first shape;assemlny 38 and itsa'tioh on the mounts: has lteeh completed; the aotiialfig means 58 effects a return of the first shaper'assembly to itspositionshown in Figures 1, Zaiid 3. The spring loaded teleseoping rod3, drawn downwardly by the primary'drive lever'ii, draws with it theactuating leve'r 2 to which it is fioiihcltd through the bearing stud 24(Figures 3 and 4). The downward movement of the lever 2 onsets thereturn stroke of the shaper Cone 5 and the sliaper eylin'der 32. Thedownward movement of thelever 2 eiieots the return stroke of theshapercone 5 through the bearing shaft 25 the'universal joints fail, the drivelinks Ti, the universaljoints 28, and the block rin whioh the manor coneis mounted (Figure 1).

Since the sharier cylinder 3?. is freely mounted on the shank portion ofthe link 10 (Figures 1 and 3), gravity efiects the first phase or thereturn stroke thereof. This phase of the return stroke is completedwhen; the baseof the cylinder 32 engages-the baseiportion of the linkIii. Further downward movement of the cylinder 32 does not takeplaceagain until the lever 2 has moved down suflieientli to engage thepositive return arm 61 on the spring-loaded lever.

During this dwell period, the cylinder drive sin 36 has been drawndownwardly through the elongated slot 33 to the bottom thereof by theshaper eone 5.- In the event that gravity did. not efiect the firstphase of the return stroke of cylinder 32, the oylinderdrive 34 willeffect the coin- Dlet returnstroke of the cylinder.

The second phase of the return stroke is efi ted 'Whenthe downwardmovement of the lever 2' depresses the lever I through the arm 67(Figiifs 1 and '2). Since the link Hi is fixedly eoniiotd through theuniversal joint tothe lever l, is downw rdly therewith, thuspermittiiigthe ylihdr drive" pin 34 to effect the remaiden the returnstroke of cylinder 32.

m fit maiiine with which the apparatus of our invei 'loii'is associatedindexes and effects rhovenl nt of tl'ie head thereofin which the mountted fro a posit on where the mount u tel" jiiitli the sliapei' assembly33 d a position Where it is in register with the secand snaper assemblyis.

As was meuu fieu above; both the first shaper asbrfiiiiv and th secondshes-per assembly is ave eonunon set-Lianne means 55. on or the upwardof the second men as is aeeempiished through the V v of its aetuating"lever I3, one are or which is fixedly nioiintd on the same shaft is whicone end of the actuating lever ed. I Thus the u ward movement ofweathering lever 2 effects the upward stroke of the second shaperassembly 39 through'the shaftlZ, the actuating lever l3, and theadjustable drive link 38. The return stroke of the second shaperassembly 39 is similarly effected.

We have found that the use of a second shaper mechanism is notabsolutely necessary. The advisability of its use will be determined inlarge part by the outside mount diameter desired. For example, if onedesired to effect a further inward displacement of the mount 52 ofFigure 11, one would use a second shaper mechanism, in which thediameter of the shaping cone thereof is smaller than the diameter of thefirst shaping cone. The second shaper assembly 39 (Figures 1, and 6) isan auxiliary shaping mechanism of this type.

Although we have described the method and apparatus of our inventionwith reference to specific mount structures (Figures 10 and 11) it willbe readily apparent to those skilled in the art that it can be readilyemployed to re-shape mounts of designs different from the one shown inFigure 10 to provide mounts of designs different from the one shown inFigure 11. It may be used to re-shape mounts which have but one or twofilament supports, or it may be used to reshape mounts having more thanthree filament supports. The tongue or tongues 4| would, of course, thenbe designed to properly effect the deformation of the desired filamentsupports.

Although in the specific example described above we have deformedalternate filament supports,

adjacent filament supports may also be deformed without departing fromthe spirit of our invention, by changing the configuration and/orrelative disposition of the tongues 4| which effect the deformation.

In some cases, depending on the initial relative disposition andconfiguration of the lead wires, the tongues 4| may also serve as leadwire separators, positioning and guiding thelead wires before they areengaged by the lead wire separators 31 and/or 45. In still otherapplications, the initial disposition and configuration of the leadwires may be such that lead wire separators 31 and/or 45 are notnecessary.
